Application filed i'ipril 9, 1909. Serial l te. icence To all whom itmay concern:

lo it known that I, FRANK PARSOSS, a citizen ot' the United States. anda resident of Boston. in the county of Suffolk and State ofMassachusetts, have invented a new and metal improvement in Cord'lerininali-i, of which the following is a specification.

My invention relates to 'cord-terminals and its object is to provide aconnecting clip that may be cheaply manufactured and by means of which aconductor may be secnrely retained in connection with a-cot'iperatinggcontact or plug, especially where the apparatus employed is subject toshock and jar-as in the case of a utomobilo or moton boat spark-plugs.

in carrying out my invention I prefer to.

employ two flat conductingmembers of spring material appropriatelyformed to provide a housing for the head of the plug with which thedevice is to be nsed and means so uniting said members that the terminalmay be snapped over said plug and elastically secured thereto, therebydispensing with locking devices or other movable members sometimesemployed with cordterminals.

The drawings which accompany and form a part of this specification showone embodiment of my invention whereby the foregoing object has beenrealized in practice.

In the drawings Figure 1 is a side view of my improved cord-terminal andits cooperating spark-plug. Fig. 2 is a central section of thecord-terminal shown in Fig. 1, and Figs. 8 and 4.- are top and bottomviews thereof respectively.

In the drawings selected for more fully disclosing my invention, 1represents a that piece formed substantially shown of any suitablematerial such as spring-hrass and provided near its front extremity witha depression or cupped portion ishown in the present instance ascircular and adapted to rec we the head 11 of the spark-plug 13.

This cupped portion may be perforated as shown at 5 for the purpose ofadapting the terminal to types of plugs other than that shown herein.

2 represents a member cooperating with the memher l and also constructedof elastic material such as spring-brass. The member 2 is provided witha slot 2 of substantially the shape of the r portion 8 of the memher 2.so that the latt :,7 be stamped from undnc waste of material. Theforward e1 cf the. members 1 and 2 are reversely beveled as shown sothat the terminal may easily be snapped oveit'the plug with which it isintended to he used. I

The iliQlill-;"" are together as by the til 1 5 and are arranged so thatthe slot and cupped portion. cooperate to form a housing tor the head ofthe plug shown in the pr nt instance at 11.. The member is provided with:1 hole 7 throng 1 which. the conductor 9 may he passed and then bentover upon the member 2 and secured thereto in any suitable manner. Inthe present instance I have illustrated one way in which the connectormay he secured a .e terminal. in this particular instance ion. of theinsulation. of the conductor as shown at M thereby exh of the conductor,the tl'ii'ough the hole 7 and an. secured to the memi;- cord orinsulating e of this particular erminal to the connection only of theterminal is execs ii iii the jarring of the motor vch h the device isemployed cannot cause any portion of the terminal to come in contactwith metallic parts of the engine and thereby cause shortcircuiting asin the case of several-types of cord-terminals now in common use.

In Fig. 2, 15 represents the can of a well known form of sparloplng andthis cap terminates in head 11 provided with a neck 12. in attaching thecord-terminal to a plug of this type the terminal is placed so that thehead 11 will enter the recess between th'e beveled edges 6 and the neck12 will. ente the slot 2. when so positiened, the corcl-terminal may heforcet torward over the head, the members 1 and 2 having sutlicientelasticity to permit terminal to be snapped over the head and secured'striobrass withont and doctors is tl thereto by their elasticity.

It will be obvious that a very firm, al-

though readily removable, connection mey-c he formed by my cord-terminalend after the'latter has been snepgied over a plug and the plngheadsecured in the tie pression or cupped yortion it will impossible toremove the terminal from t x. plug withotit first pressing downward uponthe rear 'igortion of the terminal so as to slightly lower ant therebyslightly elevate the fmni part ml the cupped yortion over the heed,whereupon the terminal may be Withdrawn from the ping. Whenever by Wear01' otherwise the members becdme ieesmietl or the parts altered, therivet connection of the members may be readilytightened.

it claim:

A cord-terminal comprising a flat body of spring material provided Withan unslotietl cupped-ea a flat body 2 of spring material provideti with:1 slot 2 underlying said cap, said slothaving substantially the shapeof the rear portion 8 of said body 2 e the n'ieinber 1 from the and thefront edges of eacn 'eisnfli 000193 being reversely beveledtoprovide an'ien i trance for the plug withAvhich the fiepjninal" is to be-used, andmeans near th end of the terminal securing said-bodies to gether so thatthe cap and slotted body form a housing Which-maybe snapped over ithe'head of alug" and secured thereto by the elasticity 0 said bodies.

In testimony whereof, I have hereunto subscribed my name this 6th day'of April 1909;
